The same argument would make C non turing complete. Because the size of pointers is a compile time constant and because everything needs to have an address that puts a large, but hard limit on tape length.
There are ways to argue arround that, e.g. C might be able to interface with a infinite tape file via the stantard library, and maybe strict aliasing and pointer provenance let's you create a system where bit identical pointers can be different. But the mental model most people have of C wouldn't be turing complete.
